determination ​(R2​) for this problem
e. Test the equation for statistical significance by examining
the population slope. Use a
0.05 level of significance. State the null and alternative
hypotheses the test.
Determine the test​ statistic:
Determine the​ p-value.
State the conclusion.
Determine the 95​% confidence interval estimate of the
population slope.
